1.1This practice serves as a practical guide for the performance testing of process stream analyzers specifically for measuring chemical or physical characteristics of liquid aromatic hydrocarbon materials for production or certification of these materials. The practice may be applicable to other hydrocarbon stream analyzers as well.
1.2Only external methods (complete substitution of the process stream with a standard) of control sample introduction are included. Internal methods are beyond the scope of this practice.
1.3Methods for resetting key operational parameters of analyzers to match predefined limits are provided by vendors and are not included in this practice.
1.5Procedures for statistically interpreting data from automatic sampling process stream analyzers are outlined.
1.6The implementation of this practice requires that the analyzer be installed according to APIRP-550 (1)2, and be in agreement with the analyzer supplier's recommendations. Also, it assumes that the analyzer is designed to monitor the specific material parameter of interest, and that at the time of initial or periodic validation, the analyzer was operating at the conditions specified by the manufacturer and consistently with the primary test method.
